Avatar
I just finished watching the movie “Avatar” directed by James Cameron.
Although it’s a very long film, the film was so good. The 3D effects are awesome. I love it even I need to wear two glasses 
Here are some definitions from wikipedia about the 3D films:
A 3-D film or S3D film[1] is a motion picture which provides the illusion of depth perception. Derived from stereoscopic photography, a special motion picture camera is used to record the images as seen from two perspectives, and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3-D films are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, primarily for marketing purposes.
